Sea Foam should be added via brake booster vacuum line or the small vacuum on the side of the throttle body......They do make a spray, however...How did you get it in? Worst scenario, hydro lock...

Unhook the batt on the car for about 1 hr to make sure. Then hook it back up. That will lose the reduced power. When you start it back up make sure you keep it running by just giving it a little gas...

How fast did you dump in the "little bit"?

Although pulling in via the brake booster or PCV orifice is typical, it doesn't really matter where it's pulled in... in fact it doesn't matter at all anyway because it's a waste of time.

I seafoamed forever, still got pinging, pulled the heads and had tons of carbon to scrape. ALL additives are snake oil.

With that being said, pull your codes (easy to do on your dash, just search if you don't know how)... write them down, clear them all... most likely the car will start. If not, other codes will be produced. Post what they are.

If you'd rather phone support, PM your number, I'll be up till midnight and I'm in good mood, I can walk you through this. Git 'er done!

Only added about ten seconds worth it was the spray that can go through the throttle plate

I agree with both of these - we need the codes and you need to reset everything "AFTER" we know the codes -

You can access them off the DIC - if you don't know how let us know.

Thanks,Matt

Wish you called, have some ideas (even without codes) but typing on this iPhone sucks.

If the engine was running and you took off the airbridge to spray in the snake oil, you were taking the MAF (mass air sensor) out of the loop, hence the reduced engine message (and corresponding code stored min the computer).

Put the air bridge back on and turn the key.

Off to bed, good luck... Zzzzz

How long did you let it sit after? Does it just turn over and not fire at all?

I thought the same thing reading the story.

You took the MAF out of the circuit by disconnecting the air bridge to spray inside the intake manifold. Not good.

Make sure to change the oil & filter. I'm sure you overloaded the cylinders and contaminated the oil as well.

I would look at make sure for your quesion to him on this. But with that code coming up on his display it will never start until that is out. Only way is to unhook the batt for a t least 1hr or to do it by the book on hold this and hit that and then do this crap with the key on acc.

Yeah ya got a good point there. I hope he got it running, a hell of a lot of guys have done the Seafoam clean-up and this is the first time I've heard of a problem. Sure it'll smoke like all get out, but the pistons will be cleaned up and his piston slap should be gone for awhile.

Highly unlikely that 10 seconds of spray "overloaded the cylinders and contaminated the oil as well".

Totally agree, if seafoam worked as well as it is reputed it should clean a carbon crusted intake valve if soaked in it right? I soaked a 40 year old intake out of the old head in my C3 for a month and when I finally remembered it was in there was no noticeable change in the hard caked carbon on the valve. People say that it is working because it is smoking when applied. That smoke is the light petroleum and naptha burning off.

I was getting pinging and knock sensor codes and Seafoam kinda worked the 1st time around for a little while... it still pinged though and in short order the knock codes were back.

I Seafoamed again to no avail, the picture below was about 300 miles after the last treatment.

When I pulled the heads, the backs of the intake valves were fairly clean and also the intake ports.... but the chambers, piston tops, and the back of the exhaust valves were hard caked. I actually needed a grinder to correct the exhaust valves, my little drill powered wire wheel had no chance.

Seafoam (and Techron) does nothing except clean the backs of the intake valves with regular use.
